J/AJ/108/1163 Radio structure of Quasars (Kellermann+ 1994) ================================================================================ The radio structure of radio loud and radio quiet quasars in the Palomar bright quasar survey. Kellermann K.I., Sramek R.A., Schmidt M., Green R.F., Shaffer D.B.=1994AJ....108.1163K ================================================================================ ADC_Keywords: QSOs ; Radio sources Abstract: Images of resolved radio sources in the Palomar Bright Quasar Survey are presented with an angular resolution of 0.5 and 18arcsec. The observed structure of some well resolved radio quiet quasars and AGN's show large scale linear structures or unresolved central cores similar to radio loud objects in the BQS sample as well as the more luminous radio selected quasars. We suggest that at least some of these less luminous radio quiet objects may contain compact central engines characteristic of radio loud quasars and radio galaxies.
